Question

我是Ruby和RoR的新手，按照RoR指南的第一步，我遇到了问题。正如他们所说in the docs，我试图安装RoR并创建一个新项目。

首先，运行gem install rails，在我看来这是宝石railties的一个问题。我又跑了gem install rails，一切似乎都很好。

但是，当我尝试生成运行rails new my_project的项目时，run bundle install内部命令中出现错误：

      create  vendor/assets/stylesheets/.keep

我已经删除了rails和railties宝石并重新安装了它们，但没有任何变化。有什么想法吗？

版本：

ruby -v ruby 2.0.0p353（2013-11-22）[x64-mingw32]

rails -v Rails 4.1.0

我正在 Windows 7（x64）

上运行

Answer 1

我找到了一个简单的解决方案。我安装了Ruby 1.9.3，现在一切正常：

ruby -v ruby 1.9.3p545（2014-02-24）[i386-mingw32]

Answer 2

尝试在其默认目录C：\ Ruby200或C：\ Ruby200-x64下安装Ruby。

Answer 3

首先使用命令

rails new yourProjectName

然后运行命令

rails s

创建服务器

Rails新项目没有很好地生成
